High-Power 355 nm Ultraviolet Laser marking PCB for permanent and clear marking
Aug 13 , 2021Since the reform and opening up, due to preferential policies in terms of labor resources, market, investment, etc., China has attracted large-scale transfer of European and American manufacturing industries. A large number of electronic product manufacturers have set up factories in China, and this has led to the development of PCB circuit boards. The development of related industries.
As the "mother of electronic products", PCB circuit boards are important electronic components, the support of electronic components, and the carrier of electrical connection of electronic components. It is the upstream of almost all electronic consumer products, whether it is mobile phones, computers, tablets, Display screens, etc., all use circuit boards, which have a wide range of applications.
The traditional silk-screen printing process is rough, and the logo is easy to fall off, causing inconvenience to users. In addition, the silk screen processing procedure is cumbersome, requiring timely replacement by operators to ensure production efficiency, which increases labor costs. With its precision and flexibility, laser marking can make up for the shortcomings of silk-screen processing, and has gradually become the best processing tool for PCB marking, and will play a pivotal role in the circuit board industry!

The laser marking technology can skip number marking, realize one item one code, and mark the two-dimensional code on the PCB, which can achieve quality traceability, allowing users to know product information with one click. Laser marking is a marking method that uses a high-energy density laser to locally irradiate the PCB board to vaporize the surface material or produce a chemical reaction of color change, thereby leaving a permanent mark. Laser marking can produce a variety of characters, symbols and patterns, etc., and the size of the characters can range from millimeters to micrometers, which has special significance for the anti-counterfeiting of products.
High precision: Laser marking is precise and non-contact processing. Thin lines below 0.1mm and characters and numbers within 0.5mm can be printed on the surface of the material. It is especially suitable for circuit boards that require very small graphics and text logos. High quality: Electronic chips have high requirements for marking quality, clarity, and permanence. The laser marking machine can achieve permanent and clear marking of the chip, and the marking will not fade due to external factors such as high and low temperature, acidity and alkalinity, and friction. Safety and environmental protection: Only a small amount of gas is produced and discharged through exhaust, without the aid of chemical substances, as far as possible to protect the safety of the operator and the working environment.
With the change of the times, laser marking is also constantly breaking through to adapt to the development of society, gradually replacing the traditional silk screen processing, bringing new vitality to the manufacturing industry in a more convenient way, and keeping up with the pace of the industry 4.0 era. The PCB dedicated laser engraving machine developed by RFH Laser can help the circuit board industry complete perfect quality traceability control, and provide circuit board manufacturers with a complete set of laser equipment processing solutions. The use of the PCB laser engraving machine can significantly improve the production and processing efficiency and product yield, save a lot of consumables costs, and the operation of the fully automatic production line also reduces labor costs, allowing your factory to be in the same Stand out from the competition in the industry and take the lead.
